The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the menu for the next couple of weeks at Kennebunk Beach.
To be straight with you, the next week and a half is mostly a write-off. We’re looking at a long, dry spell of poor surf. From Tuesday afternoon the 15th right through to the middle of the following week, conditions are just not cooperating. The swell is tiny, the wind is messy, and even when we do get a clean moment or some offshore flow, there’s just nothing in the water to ride. That’s a solid ten-day stretch of flat to knee-high slop that’s really only good for a paddle or a tan. It’s the kind of blank run that makes you want to wax your board just to feel useful.
The first real glimmer of hope pops up on Sunday the 28th. The morning of Monday the 29th actually has a bit of promise, but Sunday the 28th is where I’d pencil in a session. We’ve got a solid 3ft of SE groundswell rolling in with a very long period of 16 seconds. That’s some serious energy – the combined swell energy is pumping at a strong 505 for the morning, and even better at 684 later in the day. That’s a proper groundswell. The catch? That long period stuff can be a bit straight and dumpy on a beach break like this, so it might be a bit tricky. The wind is looking clean from the NNW and N, so the face will be smooth. It won’t be for beginners at that size, but for the experienced crew, it’s the best shot we’ve got. Later on Monday the 29th there’s still a 4ft swell (12 seconds) but the commentary gets a bit more cautious. Still, the Sunday to Monday run is the only time I’d get wet.
The water is sitting at a balmy 63°F right now, which is a touch warmer than normal for mid-September. That’s a nice bonus when the waiting game gets long.
The rest of the second week’s forecast – like the 29th and 30th – slumps right back into tiny, weak surf. It’s a tough run.
So, the standout is Sunday the 28th and into Monday the 29th. It’s the only true swell on the horizon. Keep your expectations in check, but if you’re keen, that’s your window.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
